I ran usbconfig and it = also got stuck in the same wchan. I tried rebooting it and got stuck with this on the screen.. usbus0: Controller shutdown complete usbus1: Controller shutdown=20 I have previously run the same hardware on 9.0 (where there was a panic = in devfs triggered if the DAQ card disconncted sometimes) and 9.1 (where = I have not seen any problems). Does anyone have an idea about how I could go about gathering more = information if it happens again?
